RTB or Coastal Carpet

A Boa would probably be your best bet. Humidity isnt as much of an issue with them as with BRBs or BPs. They are calmer more handleable snakes as well. They also get to be around 6-7' for a male depending on the locality. There are some Boas that get bigger than that but you should be able to find a locality that fits your needs. Btw BCIs are specifically what you need since they dont get as big as BCCs.
